Machine learning and computer vision in the real world

I lead the machine learning and MLOps teams at Onfido. We use computer vision and machine learning for online identity verification. From 2015 to 2021, I led the machine learning team for recommendation at Criteo, where we transformed the recommendation engine using a lightweight encoder-decoder architecture. From 2010 to 2014, I led the computer vision team at Thales Optronics in France.

I graduated with a PhD at MIT in 2010 under the supervision of Prof. Seth Teller. I was a core member the MIT team at the DARPA Urban Challenge in 2007. My work was published at CVPR, ICCV, ICRA and IJFR. I am a reviewer for NeurIPS, ICML and ICLR.
